Q: Hi! I just needed some advice since I am planning to get my teeth cleaned as there are nicotine stains on them. What I really want to know is that since some needle-like instruments are used by dentists, is there any risk of AIDS?

A:There is definitely a chance of getting infected by the AIDS virus if the instrument tip used for cleaning your teeth is not sterilized properly. Hence it definitely makes sense to inquire from the dentist about his sterilization techniques and so on.
